3 ^ 3 * 3 \ 2 Mod 12 * (4 – 2)

3 ^ 3 * 3 / 2 Mod 12 * (4 – 2)

If I evaluate this as written, I get
27 * 3 / 2 (mod 12) * 2
= 9 / 2 * 2
= 9
I suspect that is not what you meant, since 2 (mod 12) is just 2
So, maybe you meant something else.
Now,
3 ^ 3 * 3 / 2 is not an integer, so now I'm getting confused.
And who knows? Maybe you're a computer programmer, and \ indicates integer division. In that case, we could have
3^3 * 3/2 = 81/2 = 40
But the rest still is either trivial or stupid

So, how about some parentheses and standard "/" usage for division?

Oh, and why not? Maybe you could show your work, so we can get an idea of how you view operator precedence?...
